Help please I don't know what to do. I usually am a bit ligtheaded, dealing with a lot of stress presently, feeling anxious and nervous but today I felt really dizzy where I had to hold onto the wall so as not to fall. I got real scared, my pulse was racing. I sat down to calm down and did so after awhile. I still feel sort of light headed but my blood pressure is within normal range. I don't know what to do? Any ideas? Thank you
